a while back while playing majoras mask in snowhead temple i just basically stopped trying to complete the temple at all and got obsessed with this one tiny room where there's just 2 doors and a wolfos. i spent literally 45 minutes trying to work out the exact series of button inputs that would allow me to one-shot the wolfos in the shortest amount of time. just going back and forth through the same door. i dont even think its useful for a speedrun but it was satisfying for me at least
